BEARING'.

Specification of Letters Patent.

Application filed october 16, 1914. Serial No. 867,011.

Be it known that I, RAYNARD L. VVnrrNm, a citizen of the United States,residing at llmira, in the county of Chemung and State ot N'ew York,have invented certain new and uset'ul Improvements in Bearings, ot whichthe vfollowing is a specication.

The invention has for an object to provide a bushing for bearingsadjustable to com-- pensa for wear, whereby a journaled inember may bekept snugly engaged in the bearing and loose movement obviated.

1t is a particular object to provide a bushing and spindle boltsuitable.for situations such as connections between the steering arms on thewheel spindles of a motor vehicle and the connecting rod therebetween,and between the connecting rod and the operating rod or similarconnections.

Another object is to provide a novel and desirable mounting for thebolt.

Additional objects, advantages and features of invention will appeartrom the construction, arrangement and combination of parts hereinafterset forth and shown in the drawings, where- Figure 1 is a fragmentaryview of a spindle arm and connection partly in section. T ig. 2 is across section on the line 2 2 of Fig. 1. Fig 3 is adetail of thebushing. Fig. eiis a view similar to Fig. l of another embodiment ot'the invention.

There is illustrated a spindle arm 10 otl the usual type customarilyprovided, pivoted upon which is the usual connect-ing rod yoke l1, intothe outer end of which the connecting rod 12 is screwed. The outer endsot the arms ot' the yoke and the end of the arm l() are enlarged andprovided with the usual concentric bores, as shown in Fig. 1, the lowerot which is threaded. in the yoke, and receives the threaded endl 13 otthe bolt 14, the end 13 vot which is of thel usual size in the standardbolts supplied for such connecs tions. inwardly ot the threaded part1?), a conical portion l5 is formed on the bolt, the lower part of whichcorresponds in diameter to the minimum diameter o'l' the opening throughthe lower arm ot' the yoke 11. The bolt from this point is graduallyenlarged until it attains the diameter ot' the smooth bore 1G throughthe upper arm ol the yoke 1.1, where thcI holt is provided with a`smooth cylindrical portion 17 engaging snugly in the bore ot' the yoke,a threaded portion 18 of suitable diameter being t'ormed thereabove toextend ay distance above the yoke, the bolt being also provided with theusual hexagonal head 19 above this last mentioned threaded part. Thebolt is also bored as at 20 for .lubrication ot' the bearing, andlittedas at 21 in the customary way tor the engagement ot' oil or gr-isecup.

Fitted in the bore ot' the arm 10 there is the usual bushing 22 otbronze or other suitable metal, and engaged between this bush ing andthe bolt there is an expanding sleeve 23, of steel cylindrical on itsexterior to engage snugly within the bushing, and conical on theinterior to tit closely upon the tapered portion ot the bolt, the taperof the sleeve terminating a short distance `trom its lower end, asshown. Initially the bolt is provided with a nut 21, closely adjacentits head and is inserted downwardly through the yoke l1 and theinterposed arm l() and its bushing, into which the sleeve. 23 has beenpreviously driven. The bolt passes through this sleeve and its lowerthreaded end is engaged in the lower threaded opening in the yoke, intowhich it is screwed until the sleeve 28 has been t'ully expanded toproperly engage the bushing The bolt 2-t is then tightened, and a locknut 25 is then engaged on the lower end otl the bolt, which projectsthrough the yoke. As the bushing becomes worn, the nuts 2-t and 25 areloosened from time to time and the bolt 11 screwed inwardly and the nutsagain tightened.

The arrangement described permits` the application ot' my adjustableconstruction in connections where standard fittings and bushings havebeen employed, without change or fitting, enabling the use ot' thectstomary bushing.

ln Fig. 1 another application ot' the invention is illir-:tratcd, inwhich the bushing 2G is tapered, and the necessity 't'or the sleeve 2:3eliminated. lt will be understood that this bushing may be shaped in thesame 'ay that the sleeve 23 is, on the interior, and used in conjunctionwith the bolt4 1-1. ln this view. however, the bolt shown at 27, has asomewhat longer taper, and the bushing 2U without a cvlindrical portion.The lower reduced part of the bolt clears the opening 2S through thelower arm ot the voke 2), und a cone il() is threaded ou the lower cudsot the holt, engaged in a correspomling scat 3l lormcd in the lower sideol the yoke. A lock uut is engaged on thi,l

l end of the bolt outwardly of the cone 30.

I `The bolt is alici-'wise formed and held in .the

yoke in the same way as already described, in the irst mentionedembodiment.

In the use of this last embodiment of the invention it is simply'necessary to engage the bushing 2G in the bore through the outer end ofthe spindle arm, insert the bolt 27 downwardly through the yoke andbushing and engage the cone 30 thereon, screwing it 'up until a properbearing is secured, after which the lock nuts 32 and 24 are tightened.

Y It will be seen that an extremely simple adjustment is provided,requiring onlythe adjustment of a single bolt to take up play inbearings of this character and the device represents no objectionableexpense as .compared to the bushings customarily employed at present insuch connections.

' A`VVhat is claimed:

1. In a connection of the class` described,

a yoke, a bolt having an enlarged smooth cylindrical portion revolublein one arm o the yoke, an intermediate /tapered portion and an -outerreduced threaded portion in snugengagement in an opposite arm of theyoke, a bored element revoluble in the yoke,

a member `engaged in said element having a tapered inner portion littedsnugly on the tapered part of the bolt, and means to adjust the boltlongitudinally and secure it in adjusted position. p i

2. In a connection of the class described, a bolt having an upperthreaded portion,

an adjacent smooth cylindrical part in` olubly engaged in saidrevolublemember and having atapered opening therethrough with its largerend toward said smooth bore of the yoke; a bolt member having a reducedthreaded outer endfengaged in said threaded opening, an intermediate asmooth cylindrical portion engaged snugly and revolubly in the smoothbored arm of the yoke, a threaded portion on the bolt outwardly of saidcylindrical part and forming a continuation of said part, a head at .thelarger extremity or' the bolt and nuts en! gaged on each threaded partof the bolt outf tapered parton the bolt snugly itted in thelo'ushiiig.,`-

having a borelargcr than said smaller openv mg; a split bushing membersnugly and revwardly of the yoke, and bearing against re- I spectivearms.

In testimony .whereof I have aHiXed my signature in presence of twowitnesses.
